User manual
- Introduction
  Thermal Model Exchanger is an application that allows you to transfer thermal models between Thermal Desktop and Simcenter 3D. The application supports the transfer of the meshes, material and optical properties, and boundary conditions of your model.
- Prerequisites and operating system
  Thermal Model Exchanger requires the installation of AutoCAD with Thermal Desktop. The Thermal Model Exchanger application uses the OpenTD Application Programming Interface (API) to exchange data between Simcenter 3D and Thermal Desktop. Since OpenTD only supports C#, Thermal Model Exchanger can only run on Windows.
- Thermal Model Exchanger user interface
- How to use Thermal Model Exchanger
  - Start Thermal Model Exchanger in a new Thermal Desktop session
  - Start Thermal Model Exchanger in an existing Thermal Desktop session
  - Import a Simcenter 3D model to Thermal Desktop
    When you import a Simcenter 3D model to Thermal Desktop, Thermal Model Exchanger imports the CAE entities listed in the thermal solver input XML file generated by Simcenter 3D.
  - Export a Thermal Desktop model to Simcenter 3D
    When you export a Thermal Desktop model to Simcenter 3D, Thermal Model Exchanger reads the CAE entities used in the Thermal Desktop session, and converts the supported entities to an XML file.
- Simcenter 3D entities supported by Thermal Model Exchanger
- Thermal Desktop entities supported by Thermal Model Exchanger
- Assumptions and limitations for importing a model
  The following section describes the Thermal Model Exchanger assumptions and limitations when you import a Simcenter 3D model into Thermal Desktop.
- Assumptions and limitations for exporting a model
  The following section describes the Thermal Model Exchanger assumptions and limitations when you export a Thermal Desktop model to a Simcenter 3D Space Systems Thermal XML file.

Start Thermal Model Exchanger in an existing Thermal Desktop session

Start Thermal Desktop.
In the bottom command line, type RCOPENTDV62 and press enter.
This command starts the OpenTD version 6.2. When you use a different OpenTD version, replace the last two digits with your version number.
Type Client and press enter.
This specifies the name of the server endpoint.
Run the MayaThermalExchanger.bat file to start the Thermal Model Exchanger application.
The Thermal Model Exchanger executable connects to the existing Thermal Desktop session and opens the Thermal Model Exchanger window.
